SHEEP-SHEARS,

SPECIFICATION" forming part of Letters Patent No. 740,523, dated October 6, 1903.

Application filed May 19, 1902.

To all whom it may concern: Be it known that I, "JUAN F. BURGHER, a

, citizen of the United States, residing at Belt, in

act description of the invention, such' as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to shears, and more particularly to that class known as sheepshears and it has for its object to provide a tool of this nature from which the blades may be easily and quickly removed to facilitate sharpening or for substitution of other blades.

A further object of the inveution'is to provide a construction which will insure against lateral springing of the blades from their proper operative positions, other objects and advantages of the invention being understood from the following description.

In the drawings forming a portion of this specification, and in which like numerals of reference indicate similar parts in the several views, Figure 1 is a side perspective view of shears embodying the present invention. Fig. 2 is a top plan view of the upper member of the shears. Fig. 3 is a section through one of the blades and the arm to which it is attached. Fig. etis a detail perspective view of one of the detachable blades.

Referring now to'the drawings, the present shears comprise the two arms 5 and 6, which are curved transversely to prevent injury to the hand of the operator, and the rear ends of which arms are flattened transversely and then bent into hook form, as shown at 7 and 8, thefree ends on bills of the hooks being riveted together. The arms are of spring metal, and'the hooks are resilient, so that the arms may be moved toward and away from each other in the ordinary process of shearing.

The free or'outer ends of the arms 5 and 6 are compressed laterally, so that two spaced wings or plates 9 and 10 are produced, and between these wings of each arm isdisposed the reduced rear portion of the upper part of a blade 11, the recessed faces of the blade 11 The wings between which each blade is dis- Saris-1N0. 107,979- (No model.)

receiving the wings, so that the latter lie flush with the side faces of the blade.

Through the outerend portions of the wings 9 and 10 are formed alining perforations l2, and in the blade 11 is formed aperforation 13 so positioned that when the reduced portion of the blade is disposed between the wings, with the rear end of the reduced portion against the shoulder 14 and the shoulders 15 of the blade against the inner edges of the wings, the several perforations will aline to receive-a pivot-pin 16. It will be noted that at the rear end of the blade the blade proper projects beyond the reduced portion, so that a shoulder 17 is formed which engages against the inner face of the arms at the base of the wings. The position of the pivot-pin 16 adjacent to the outer ends of the wings permits of theuse of a single pin for holding the blade in place.

7o posed tend to lie in mutual contact, and when the blade is to be inserted or removed the wings must be forced apart. The pin is carried by one of the wings between which the bladeis held, and when the wings are sprung apart the pin is withdrawn from the blade and it may be removed. a

On the inner face of each of the arms 5 and 6 and at the bases of the wings of the latter are formed the two lugs 17"and. 18, which are in planes at right angles to each other, and the inner ends of these'lugs are transversely slotted, so that when the arms are moved toward each other to their limit the slot of one lug will receive the other lug, and the sides of the slots will prevent lateral displacement of the arms, the lugs themselves acting as stops.

In practice modifications of the specific construction shown may'be made, and any suitable materials and proportions may be used for the various parts without departing from the spirit of the invention.
